Different jewelry metals respond differently to laser energy. This guide explains how to adapt settings by metal for clean, legible marks.
Gold and silver
Highly reflective precious metals usually mark best with controlled power and optimized frequency to build contrast without excessive heat.
Stainless steel
Stainless takes deep, durable marks and annealed black marks well, making it forgiving for serial numbers and logos.
Brass
Brass marks cleanly and is common for fashion jewelry and samples; settings are similar to other non-ferrous metals.
Testing before production
Always run a short test on scrap of the same alloy before committing a production batch, then save the profile for repeatability.
